The table below shows how each service (anonymized as P1 - P5) fare in terms of conversion rate for African countries: Ghana (GH), Nigeria (NG), and Uganda (UG). This data is used to answer the questions asked.
From Table 1, we can look at the data for each service to derive Table 2:
We look at Reliability and Sensitivity.
Thus in Africa, if you do not have voice & SMS verification service reliability data, you can pick an outright poor service, which results in bad user experience, and major loss of potential & existing users; there is a 35.87% difference in average OTP reliability (between the worst and best OTP provider)
The effect of using a 2-service combination, is very obvious; the average Reliability across any 1-service 60.10% (from Table 2 but calculation not shown) jumps to 70.46% (from Table 3a but calculation not shown) when any 2-service combination is employed. You can see the color code for Reliability in Table 2 moving from purple and red to mostly yellow in Table 2.
The Sensitivity of any 2-service provide across all African countries is also less, i.e., OTP deliverability is more stable across countries; the Sensitivity average & variance for 1-service combination is 21.25% and 0.012%, compared to that of a 2-service combination 16.94% and 0.013%.
By selecting the best services (Table 2), the best 2-service combination (Table 3), and deriving the measurements for 3-service combination (Table 3b), we create a Strategy table (Table 4) as shown:
2-service and 3-service combination is superior to 1-service average Reliability by more than (70.46% - 60.10%) = 10.16%, and reduces average Sensitivity by more than (21.25 - 16.94) = 4.31%.
Let us answer the questions posed about voice & SMS verification service in Africa:
In Africa, there are more phone verification services that has poor reliability because the phone infrastructure is less mature, and it is difficult for a single voice & SMS verification service to be reliable across a large number of countries. Thus choosing this right voice & SMS verification service is really crucial. In other words, don’t risk choosing a wrong voice & SMS verification service, use RingCaptcha because we know the best voice & SMS verification service/country combination for Africa.
For best practice, always use at least 2 services so that you can send a re-request for OTP, or auto-send an unconverted OTP through a fallback service. This is seldom done in practice because:
With RingCaptcha, you only maintain a single relationship with our SMS/voice OTP provider marketplace, develop for a single API, and you are never locked-in to any specific voice & SMS verification service. What is more we build in all these OTP fallback features plus fraud mitigation features so you don’t have to - you just make a single API call to send OTP, and everything else magically happens in RingCaptcha.
